| Zusammenfassung: | A fast response, low-pass filter comprising a slow response low-pass filter and a fast response low-pass filter. Both of these low-pass filters receive an input signal, and their respective outputs are compared to each other. When the output of the slow response filter differs from the output of the fast response filter by a predetermined value, the response time of the slow response time filter is increased so that it can more rapidly follow the input signal. The fast response time low-pass filter can be implemented with either analog low-pass filters or by digital low-pass filters. |
